Abstract
The invention relates to a JN15-315 type earthing switch. A bent plate of the earthing switch is provided with a meso-position jury strut, which comprises two positioning plates, a shaft sleeve, a screw rod and a nut, wherein each positioning plate is provided with a hole, the screw rod penetrates through the holes in the two positioning plates in a connection manner, one end of the screw rod is in screwed connection with the nut, and the shaft sleeve is sleeved on the screw rod. The earthing switch has the beneficial effects that the meso-position jury strut additionally arranged in the earthing switch can be used to largely buffer the impact force of a spring so as to achieve the purpose of protecting a contact knife and a contact head of a contact tube.
Description
Technical field
The invention belongs to field of mechanical technique, particularly relate to a kind of earthed switch.
Background technology
Existing earthed switch, without meta jury strut, easily cause in multi-pass operation process contact tube bend, contact knife be out of shape, even damage contact have a strong impact on its operation with its electric conductivity.
Summary of the invention
The object of the invention is the deficiency overcoming above prior art, and the JN15-315 type earthed switch providing a kind of reliability high, specifically has following technical scheme to realize:
Described earthed switch, the bent plate of described earthed switch is provided with meta jury strut, described pillar comprises two pieces of location-plates, axle sleeve, screw rod and nuts, location-plate is provided with hole, described screw rod is connected in the hole of two location-plates, one end of described nut and screw rod spins, and described axle sleeve is socketed on screw rod.
The further design of described earthed switch is, described bent plate is provided with contact knife, and described contact knife is provided with axis hole, and the hole of described axis hole and location-plate is on same level line.
Advantage of the present invention is as follows:
In earthed switch, increase meta jury strut, can the impulsive force of buffer spring in a large number, thus reach the object protecting contact tube contact knife and contact.
Accompanying drawing explanation
Fig. 1 is the structural representation of JN15-315 earthed switch.
1-bent plate, 2-contact knife, 3-axis hole, 4-screw rod, 5-axle sleeve, 6-location-plate, 7-nut.
Embodiment
Below in conjunction with accompanying drawing, the present invention program is described in detail.
Contrast Fig. 1, JN15-315 type earthed switch provided by the invention, the bent plate 1 of earthed switch is provided with meta jury strut, pillar comprises two pieces of location-plates 6, axle sleeve 5, screw rod 4 and nut 7, location-plate 6 is provided with hole, screw rod is connected in the hole of two location-plates, and one end and the nut 7 of screw rod 4 spin, and axle sleeve 5 is socketed on screw rod 4.Bent plate 1 is provided with contact knife 2, and contact knife 2 is provided with axis hole 3, and axis hole 3 is on same level line with the hole of location-plate.
In this earthed switch, increase meta jury strut, can the impulsive force of buffer spring in a large number, thus reach the object protecting contact tube contact knife and contact.
